Hi Ken,<br> Thanks for the clarification. I think a little more information is needed as I am<br>running into some problem that I can't seem to resolve.<br><br>I am using 3 machines of my cluster all three are connected to 3 displays. I want
<br>use 2 of them as multi-tile display with 2 tiles. I have the Paraview GUI on the <br>third machine. All three have X servers running and are MPI enabled. So here<br>is how I launch the jobs on the machines.<br><br>$ mpirun -n2 -hostlist "sva11 sva12" /bin/env DISPLAY=:0 pvserver -tdx=2 -tdy=1
<br><br>and I launch the client <br><br>$ paraview<br><br>and then connect to sva11.<br><br>My servers.pvsc looks like<br><br><Servers><br> <Server name="builtin" resource="builtin:"><br>
<ManualStartup/><br> </Server><br> <Server name="fw-sva10" resource="cs://sva10:11111"><br> <ManualStartup/><br> </Server><br> <Server name="fw-sva11" resource="cs://sva11:11111">
<br> <ManualStartup/><br> </Server><br> <Server name="fw-sva12" resource="cs://sva12:11111"><br> <ManualStartup/><br> </Server><br><Server><br><div class="gmail_quote">
<br>But the window multi-tile window appears only on sva11 and it doesn't<br>span the whole screen (which it used to do previously). And it doesn't seem<br>like sva12 is even doing anything. I suspect this because sva11 flickers
<br>when the client connects, but sva12 remains as it is.<br><br>If I do the reverse and connect the client to sva12, then model window appears<br>on sva12 and sva11 seems to do nothing.<br><br>Is there anything I am missing ?
<br>I am using Paraview 3.2.1.<br><br>Thanks,<br>Manju<br><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
What you are trying to do does not work because ParaView is not supposed<br>to run like that. When running in client/server mode, ParaView connects<br>to process 0 of the server, and nothing else. All communication with the
<br>client goes through process 0, and process 0 of the server uses the MPI<br>interconnect to pass data to and from the other nodes in the server.<br><br>ParaView is implemented in this way for convenience and scalability. It
<br>is not scalable to have every process in the server to connect to the<br>client because all communication will eventually have to go through the<br>same network interface on the client side. Also, the MPI interconnect on
<br>the server is almost always faster than the socket communication between<br>client and server.<br><br>-Ken<br><div><div></div><div><br>> -----Original Message-----<br>> From: Manjunath Sripadarao [mailto:

<br>><br>> I did this too, I am using a machines file for this (which we call an<br>app<br>> file<br>> but all the same). But how do you get the client to "listen" to 2 or<br>> more servers ?<br>

<br>><br>> If I write a servers.pvsc file with a list of servers, how do I get<br>> paraview pick the file automatically and connect to all the servers ?<br>><br>> Thanks in advance,<br>> Manju<br>><br>
